HORSE HAYFRA'KE,

SPECIFICATION forming part of Letters Patent No. 292,218, dated January22, 1884.

` Application filed August 1, 1882. (No model.) j i To @ZZ whom t mayconcern: f

Be it known that I, WILLIAM I-I. HALL, o Tiffin, in the county of Senecaand State of Ohio, have invented certainl new and useful Improvements inHorse HayRakes, of which the following is a specification. v

My invention relates particularly to the rake-tooth and its fasteningsand to the mode of attaching the metallic stub-axle `to the Io woodenrake-head or through-axle; and it consists in forming the 'rake-toothwith an elongated bend in its coil, which bend rests against the back ofthe rake-head to set the main coil out from the head; in forming-therakeltooth with an elongated bend in its coil to set the main coil outfrom the back of the rake-head,

and carrying the shank beyond said bend vertically up along the rearface of the rakehead, and then bending it in to afford a tang to enter asocket in said rake-head and securing it by a hook-bolt; in forming therake-4v head with sockets in its face near its top to receive the bentupper end or tang of the rake-tooth, perpendicular grooves beneath 2 5these sockets to receive the shank, and perforations to one side or" thegrooves to receive a hook-bolt,wherebytl 1e fastening is renderedcomplete, in seating the stub-axle in a casting at the end of the woodenaxle or rakehead, positioned by means of a rib or flange taking into agroove in said head, and also at .its rear endin another vcastinglikewise positioned and aligned with the first, and securing axle andcastings by means of an eyebolt 3 5 snugly inclosing the axle andpassing through the first-mentioned casting, and 4of -astraight boltpassing directly through the axle and second casting, and both into andthrough the rake-head; in an end casting for the wooden 4o axleorrake-head, formedwith a socket for the stub-axle, a rib or ribs to entergrooves lin the wooden head and determine its position, a shoulder toabut against the end of the head, and a sand-band to protect the hub ofthe wheel, and in the various other combinations and details ofconstruction hereinaften set forth and claimed.

In the drawings, Figurel affront elevation, `partly in section, ofaurakehea d, stub- 5o axle, and accessories embodying Amy invention;Fig. 2,-a bottom plan viewof the same;

head A may be attached'to the rakecarriage or frame in any suitablemanner and Voccupy anysuitable position-as, for instance, it may .behinged above the fixed axle, or behind it, or

to the frame, or may itself serve as the body part of an oscillatingaxle, the latter being the form which I have chosen for illustration.

In the rear face, and near the` upper side or top of the head, is formeda series of sockets,

c, one socket for each rake-tooth B, to receive the bent upper end ortang Zr of said tooth,

and lower down, and far enough to one side of each socket to let theshank bf of the tooth ,l

stand perpendiculanis bored-a hole, c', of

suitable size to receive the hook-bolt C, ywhich l.

on the opposite `face of the head `is secured by a nut, c, or otherwise,as may be desirable.

Beneath each socket, and in line therewith, is

preferably cut a shallow groove or channel, d, in which the shank restswhen in proper position.

As the shank portion -leaves the headY the tooth is bent outwardlyandupwardlyinto a coil of one or more turns, the rst bend be-j ingelongated, so, that it will overset the return bendand succeeding coilsat f suciently to hold them out away from contactw-ith the rear face ofthe headwhenthe shank' is drawn tight bythe hook-bolt in completing thefastening. Y Y

In lassembling the parts as thus far described,

one tooth is taken at a time, its tang insertedin the socket, and itsshank laid in the groove.

The r`hook-bolt is then putin place and .clamped down upon the shank bymeans of its nut, and

the attachment is secured. Strains upon theftooth when in` use will comeupon the hookbolt, which can at any time be tightened, in stead of uponthe tang. Brokenteethcan readily be replaced by temporarily loosening orfremovingjthenbolt;

For thepurposeof attaching thestub-enfile G to the rake-head or woodenaxle, as the case may be, the latter has acouple of longitudinalgrooves, h and h', the first near its end, and the second fartherinward, but in line with the former. The casting I is formed withasemicylindrical seat, e', to receive the body of the stub-axle, a rib,i', to take into the groove 7L in the wooden beam or head and determineits position relatively thereto, a sand-band, i, to cover and shield theinner end of the wheelhub, and, preferably, a shoulder, i, to abutagainst the end of the beam or head and serve as an additional means ofsteadying. It is also bored or transversely slotted, as at il, toreceive the shank or neck of an eye or hook bolt, H, and has bulges oneach side of the bore, to admit the body part of the ring or eye of saidbolt. Another casting, K, is also formed with a semi-cylindrical seat,k, to receive the inner end of the stub-axle, a flange, k', to enterinto the groove 71, and position the casting and align its seat with theseat in the foregoing, and is bored at k for the passage of the straightbolt L diametrically of the axle. These castings being rst put in place,the eyebolt is slipped over the body of the stub-axle, closely embracingit, then passed through the bore in the first casting, and through anaugerhole in the wooden head or axle, and clamped tight by means of anut, as shown, it-s neck drawing into a transverse groove, h2, in thehead, securing the stub-axle in its seat, and at the same time securingthe casting I solidly to the wooden part against both longitudinal andlateral displacement. The straight bolt L is then passed through thewooden head, the casting K, and a hole in the inner end of the axle, andalso drawn tight and clamped by a nut, securing at once the inner end ofthe axle and the casting in which it is seated, and the fastening of thestub-axle is completed.

It is obvious that the grooves in the rakehead beneath the tang-socketsare not strictly essential to the securing of the rake-teeth, yet theyadd largely to the beneficial character in this, that without them theperpendicularity of the shank and consequent alignment of the toothwould depend upon the hook-bolt, and the holes for the latter musttherefore be nicely spaced with reference to the socket; but with themthe tooth will be properly located, even should the hole for the bolt bea little out of the way. It is also apparent that the sandband on thecasting at the end of the wooden rake-head or axle may be omittedwithout impairing the efficacy of said casting in its function as ameans of securing the stub-axle to the head. I do not limit myinvention, therefore, so far as to require absolutely the presence ofsuch grooves or of the sand-band in the respective constructions; but

I claiml. A rake-tooth of the form shown-that is, having theinwardly-bent upper end or tang to enter a socket in the rear face ofthe rakehead, the perpendicular shank to lie vertically along said rearface beneath the socket, the coil, and the body part or tine.

2. A rake-tooth formed with a straight shank to lie against the rearface of the rake-head, and with the rst bend of its coil elongated tooverset the return and succeeding bends.

3. rlhe wooden rake-head having sockets in its rear face near its top,to receive the tang of the tooth, and perforations lower down and to oneside of a perpendicular line from the corresponding sockets to receive ahook-bolt, whereby the shank of the tooth is firmly clamped.

4. The wooden rake-head having sockets in its rear face nea-r its top,to receive the bent upper end or tang of the tooth, perpendiculargrooves beneath these sockets to receive the shank of the tooth, andperfor-ations to one side of the grooves to receive a hookbolt, wherebythe fastening is rendered coniplete.

5. The combination of the wooden rakehead having sockets andperforations along its rear face, in the relative arrangement set forth,the rake-tooth having the bent upper end or tang, perpendicular shankand coil, and the hook-bolt, substantially as described.

6. The combination of the rake-head or wooden axle, grooved at its ends,as described, the castings having ribs to take into said grooves, andseats for the body or shank of the stub-axle, the neyebolt fitting overthe stubaxle and passing through the end casting and wooden head, andthe straight bolt passing through the inner end of the axle, the secondcasting, and the head.

7. The combination of lthe rake -head or wooden axle longitudinallygrooved near its end, the castings having ribs which enter said grooves,and also seats to receive the metallic stub-axle, the eyebolt iittingover said axle and passing through the transverse slot in the endcasting and through the wooden head, its neck being drawn into atransverse groove in said head, and the straight bolt passing throughthe inner end of the axle, the underlying casting, and the wooden head,substantially as described.

8. The end casting having a seat for the rcception of the stub-axle, abore or slot for the passage of a bolt attaching stub-axle and castingto the wooden head, and a sand-band for the protection of the inner endof the wheelhub.

9. The end casting formed, substantially as described, with a seat forthe stub-axle, a rib to take into alongitudinal groove in the woodenhead, and a sand-band to cover and protect the inner end of thewheel-hub.

10. The end casting formed, substantially as described, with a seat forthe metallic stubaxle, a rib or iange to take into a longitudinal groovein the wooden head, and a shoulder to abut against the end of said head.
